Raspberry plant named ‘DrisRaspSeven’

ABSTRACT

A new and distinct variety of raspberry plant named ‘DrisRaspSeven’ particularly distinguished by having a self-fruitful plant that bears large, bright red berries, is disclosed.

Genus and species: Rubus idaeus L.

Variety denomination: ‘DrisRaspSeven’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry varietydesignated ‘DrisRaspSeven’ and botanically known as Rubus idaeus L. Thisnew raspberry variety was discovered in Santa Cruz, Calif. in August2005 and originated from a cross between the proprietary female parentraspberry plant ‘Driscoll Cardinal’ (U.S. Plant Pat. No. 14,903) and theproprietary male parent raspberry plant ‘Driscoll Maravilla’ (U.S. PlantPat. No. 14,804). The original seedling of the new variety was firstasexually propagated at a nursery in Santa Cruz, Calif. ‘DrisRaspSeven’was subsequently asexually propagated and underwent further testing at anursery in Santa Cruz, Calif. for seven years. The present invention hasbeen found to be stable and reproduce true to type through successiveasexual propagations via tissue culture and root cuttings.

Plant Breeder's Rights for this variety have not been applied for.‘DrisRaspSeven’ has not been made publicly available or sold more thanone year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Santa Cruz, Calif.:

-   -   1. Self-fruitful plant; and    -   2. Large, bright red berries.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographswhich show fruit of the plant as well as the primocanes. The colorsshown are as true as can be reasonably obtained by conventionalphotographic procedures. The photographs are of plants that are sixmonths old.

FIG. 3 shows close-up views of typical flowers and fruit at variousstages of development.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘DrisRaspSeven’. The data which define thesecharacteristics is based on observations taken in Santa Cruz, Calif.from 2005 to 2011. This description is in accordance with UPOVterminology. Color designations, color descriptions, and otherphenotypical descriptions may deviate from the stated values anddescriptions depending upon variation in environmental, seasonal,climatic and cultural conditions. ‘DrisRaspSeven’ has not been observedunder all possible environmental conditions. The botanical descriptionof ‘DrisRaspSeven’ was taken from six-month-old plants. Color referencesare primarily to The R.H.S. Colour Chart of The Royal HorticulturalSociety of London (R.H.S.) (2007 edition). Descriptive terminologyfollows the Plant Identification Terminology, An Illustrated Glossary,2^(nd) edition by James G. Harris and Melinda Woolf Harris, unless whereotherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘DrisRaspSeven’ differs from the proprietary female parent ‘DriscollCardinal’ (U.S. Plant Pat. No. 14,903) in that ‘DrisRaspSeven’ has amedium number of young shoots, medium glaucosity on primocanes, andleaves with medium relief between the veins, whereas ‘Driscoll Cardinal’has many young shoots, weak glaucosity on primocanes, and leaves withweak relief between the veins. Additionally, ‘DrisRaspSeven’ has largefruit with an easy adherence to the plug, whereas ‘Driscoll Cardinal’has medium sized fruit with medium adherence to the plug.

‘DrisRaspSeven’ differs from the proprietary male parent ‘DriscollMaravilla’ (U.S. Plant Pat. No. 14,804) in that ‘DrisRaspSeven’ hasterminal leaflets with an obtuse base and a crenate margin, whereas‘Driscoll Maravilla’ has terminal leaflets with a round to cordate baseand a doubly serrate margin. Additionally, ‘DrisRaspSeven’ has longconical shaped fruit with medium firmness, whereas ‘Driscoll Maravilla’has ovate shaped fruit that is firm.

‘DrisRaspSeven’ differs from commercial variety ‘DrisRaspThree’ (U.S.Plant Pat. No. 23,477) in that ‘DrisRaspSeven’ has a medium sized planthaving a semi-erect new cane growth habit, whereas ‘DrisRaspThree’ has alarge sized plant having an erect or upright new cane growth habit. Inaddition, ‘DrisRaspSeven’ has large sized fruit with medium sizeddruplets, whereas ‘DrisRaspThree’ has medium to large sized fruit withlarge sized druplets.

We claim:
 1. A new and distinct variety of raspberry plant named‘DrisRaspSeven’ as described and shown herein.
